ALFRED M. CHAFFEE, OF OXFORD, MASSACHUSETTS.

CONSTRUCTION OF CLOTH-BOARDS.

To all whom it may concern:

Be it known that I, ALFRED M. CHAIFEE, a citizen of the United States, residing at Oxford, in the county of WVorcester and State of Massachusetts, have invented a new and useful Construction of Cloth-Boards, of which the following is a specification, reference being made therein to the accompanying drawings.

This invention relates to an improved construction for cloth-boards or winding-boards such as are employed for winding piecegoo-ds, silks, woolens, felts and other similar cloth or fabrics; the object of my invention being to provide a stronger, more efiicient, and non-warpable construction that can be manufactured with economy and practical facility.

To this end my invention consists in producing a cloth-board in which the longitudinal side bars of the frame are made from thin sheet-metal or the like, formed hollow with a U-shaped or approximately semi-cylindrical cross-section, in combination with transverse members having rounded ends that fit within the hollow of the side-bars and support the same; the whole being rigidly secured together and a smooth even surfaced exterior produced thereon, by a covering of one or more plies of suitable paper fabric.

This novel construction is more fully ex plained in the following detailed description; the particular subject matter claimed being hereinafter definitely specified.

In the drawings, Figure 1 represents a perspective view of a complete cloth-board. Fig. 2 is a plan view of the frame without the exterior covering. Fig. 3 represents, on somewhat larger scale, the cross-section at line X X, of one of the side-bars. Fig. 41 is a cross-section at line Y Y, showing the frame-connecting oint and a portion of the external covering. Fig. 5 shows, by side and plan, the shape of the ends of the crosspicces as prepared for assembling in the frame. Fig. 6 is an enlarged cross-sectionform of the side-bar, similar to Fig. 3 at line X X, and Fig. 7 is a like section illustrating a modified edge form.

In referring to the drawings, the numeral 12 indicates the longitudinal members or side-bars of the frame; 13 the transverse members or cross-pieces, located at the ends of the board; and when required at one or more intermediate positions in the length Specification of Letters Patent.

thereof; and 15 indicates the incasing sheet forming the exterior contour and surface of the completed cloth-board.

In constructing a cloth-board according to my invention, the side-bars or longitudinal members 12 of the frame are each formed of a strip of thin sheet-metal bent trans versely to a U-shape, or to have an approximately semi-cylindrical hollow cross-section, as at 2, and with edge portions 1 that extend somewhat beyond the half circular portion, as best shown in Figs. 3, 6 and 7. In its longitudinal direction the bar is made straight with the same cross section throughout. The extended portions 41 are best slightly inclined inward or toward each other, so that the dis tance between them from one to the other is somewhat less than the diameter of the cylindrical portion; and preferably the extreme edges are slightly curved outward, as at 5 on Fig. 6. If desired the extended edge portions 4 can be made transversely parallel with each other, as in Fig. 7 or in other instances formed with or without the in wardly set lip 7 thereon.

The cross-pieces 13, which as shown are made of wood, are formed with rounded ends 3 to fit the interior hollow of the semi-cylindrical metal bars, and are reduced across their top and bottom faces, as at 8, to receive the extended edge portions 4 of the sidebars 12, so that the faces 9 of the cross-piece will be approximately flush with the external diameter of the semi-cylindrical metal sidebars, while the edges of the metal are a little below the flush alinement. These frame members 12 and 13 are assembled by inserting the rounded heads 3 of the cross pieces between the opposite edges 1 of the hollow metal side-bars, and against the interior of the cylindrical portion 2; the metal by its springing capacity yielding sufiiciently for the entrance thereof, and then resiliently closing in against the oppositely reduced faces 8 with a firm grip thereon; thus giving a readily assembled strong connection without requiring any nailing of the joints, while the ends support the sheet metal sidebars from the interior, and maintain the cross-sectional contour thereof at the ends and at any desired intermediate stations; thus preventing any liability of crushing in the edges of the clothboard laterally. This frame when assembled is coated withglue and inclosed in a casing of paper or like fabric 15, wound about it in one or more plies; the plies being smoothly laid thereon and upon each other, and united together throughout their adjacent surfaces by glue or other adhesive substance, as heretofore employed; and said paper is best shrunk in position.

As I have heretofore, in practice, long employed the idea of covering cloth-Winding boards with plies of paper shrunken thereon, it will be understood that I do not herein broadly claim that feature per 86 as of my present invention.

What I claim as of my invention and desire to secure by Letters Patent isp 1. A cloth-board construction including a frame consisting of a pair of longitudinally straight hollow side-bars made of sheetmetal of approximately uniform U-shaped cross-section, said side-bars oppositely disposed with their open sides toward each other; in combination with a plurality of rectangular wooden crosspieces having their ends respectively shaped to correspond with the interior cross-section and interlockingly engaged within said hollow sheet-metal sidebars, connecting and supporting the same, and maintaining the cross-section contour thereof, substantially as set forth.

2. A cloth-board embodying the construction set forth, consisting of longitudinal sidebars made of thin sheet-metal formed of ap proximately semi cylind "ical cross-section shape, with extended inwardly inclined edges; in combination with crosspieces having rounded ends and reduced faces fitting the semi-cylindrical hollow interior of said sheet-metal side-bars, and between said inwardly inclined edges, and an exterior casing of paper fabric wound about and adhesively united therewith in a smooth unbroken surface.

3. A cloth-winding board comprising longitudinal side-bars made of sheet-metal and having a cross-sectional shape consisting of a semi-cylindrical main portion with oppositely resilient edge portions that slightly incline inward and then curve outward; in combination with end members or crosspieces of a thickness equal to the diameter of the semi-cylindrical side-bar, said crosspieces having rounded ends and reduced faces adapted for transverse insertion within said hollow sheet-metal side-bars, and interlocking between the inwardly inclined edge portions thereof, and an external surface covering, of shrinkable fabric securing said parts together.

Witness my hand this 28th day of April, 1913.
